Can you describe gamete intrafallopian transfer (gift)?

GIFT. Gamete intrafallopian transfer (gift) is a surgical procedure, typically performed via laparoscopy, where sperm and eggs are transferred into the end of the female's fallopian tube. The eggs fertilize in the tube and the resulting embryo migrates to the uterine cavity where it implants.
GIFT. Gift involves stimulating the ovaries with gonadotropins, recovery of oocytes (usually) via ultrasound guidance, followed by immediate insertion of the best eggs and partner's sperm in the fallopian tubes. This requires laparoscopy, so gift is more invasive than ivf. The key biological difference with ivf is fertilization (if it occurs) happens naturally in the body, instead of the laboratory.
